Noviter- NSTB type steam boiler, its design can produce both
superheated steam and saturated steam. It is the single drum
natural cycling boiler, the furnace is membrane water wall
structure, convection bank is equally surrounded by membrane water
wall.
Every Noviter NSTB type steam boiler are custom-madethe company may
design and produce NSTB steam boiler that evaporation is 20 ~
200t/h in accordance with the various special needs of
customers production design , the fuel is liquid or gaseous
fuels, usually the design pressure can reach 4MPa, it also can
design higher pressure boiler.
Noviter company adopts the most advanced design tools, and combined
with years of the conventional boiler design experience,
manufacture excellent quality and reliable running steam boiler.
In order to reduce the cost of the boiler auxiliary equipment and
conducive to use, maintenance and start, NSTB steam boiler adopts
single burner layout below 80t/h capacity.
In order to use all available energy as much as possible and
heighten boiler heat efficiency, Noviter Company set a boiler
energy device (economizer) at the boiler outlet after fuel analysis
and various calculations.
Full 3d computer aided design calculation
Noviter NSTB steam boiler thermal calculation、hydrodynamic
calculation and heated side wall temperature calculation according
to the latest computational fluid dynamics (CFD) and numerical heat
transfer (NHT) principle, adopts the international advanced FLUENT
software, precise calculate every point temperature in the furnace,
combustion product distribution and heat side wall temperature
distribution, so as to reasonably guide the heating surface layout,
make each heating surface heated evenly, prolong boiler service
life and save steel .The right picture is the result that Noviter
company technical experts use FLUENT 5.0 software made by full 3d
computer simulation to the static pressure distribution in the
boiler header
The world's first initiated of vertical top-blown arrangement
Noviter NSTB steam boiler adopts vertical structure, and
relies on ground support, so the structure is compact, cover an
small area, Meanwhile, no complex piping systems and bearing
system, facilitate the installation and maintenance of boiler. The
burner is located at the top of furnace, make the furnace flame is
good, reduce the smoke blind Angle, increase the thermal
efficiency, and ensures the reliability of the water cycle.
full membrane wall structure
Due to the furnace adopts membrane water wall
structure, so it can fully absorb radiant heat of the flame, and
improve sealing of furnace, at the same time, because of furnace
wall does not receive flame radiation directly, thereby it can
doesn't need refractory materials; Convection bank are surrounded
by membrane water wall, make the sealing of convection bank is
good, so also doesn't need refractory material, make the weight of
furnace wall reduced greatly, and reduce the workload of boiler
installation and debugging at site.
Powerful low-pollution discharge function
In the combustion technology adopts the world advanced low
NOx burner, using the latest classification air distribution and
gas recirculation technology, greatly restrain the nitrogen in fuel
change to NOx in the combustion process, In the meantime, the big
furnace chamber structure reduced the whole volume heat load, make
the chamber temperature level is low, inhibit the nitrogen in
combustion air change to NOx:
big range of Load adjust
well-designed burner、rational radiation and convective
heating surface area allocation make the boiler work stably in wide
load and output the qualified parameters steam.
high automation degree
Burner purging, ignition, output power
regulation; Boiler output water temperature, pressure, rate of flow
etc output parameters test, adjust, And the boiler protection and
interlocking etc can auto-complete when the fault happens (such as
ignition failure, main thermal parameter off-gauge), and it is
stable and reliable.
